The last time Tar'Dajah saw her friend, they climbed on treadmills in a hotel and cranked the speed up, sprinting along until they tripped, fell and went flying off.

"We were just having a time," Tar'Dajah said.

Zyanna was one of those girls who made you laugh, Arp said.

"So much energy and life," she said. "You couldn't help but laugh at her and with her at the same time. She just didn't really care what people thought about her. She just lived her own little story, and if you thought she was funny, great. And if you didn't, great."

Zyanna was close friends with 9-year-old Zoie Nash, her mom, Misti Nash, said.

The pair loved to hang out, go to sleepovers together and dance. Zoie looked up to Zyanna like a big sister.

They'd ride the bus together, and sit together too.

After the crash, first responders found the two girls' bodies together, Nash said.

She shook her head.

"The thought of not seeing them two together again is just really breaking my heart," she said.
